Mar 13, 2020 · Types of Electromagnetic Waves. There are seven types of electromagnetic waves – radio wave, microwave, infrared, visible light, ultraviolet, x-rays, and gamma rays. 1. Radio waves. As the name suggests, radio waves are emitted by radio stations, TV stations, and cellphone towers. They have a wavelength range of 1-10 5 meters.
Aug 29, 2023 · The electromagnetic spectrum is the continuous spectrum of electromagnetic radiation. It covers an enormous frequency range, from about 1 hertz (Hz) at the extreme low end to over 10 25 Hz at the high end, with no gaps in the frequency range. Electromagnetic radiation refers to the waves of the electromagnetic field, propagating through space ...
Aug 10, 2016 · An electromagnetic wave can also be described in terms of its energy—in units of measure called electron volts (eV). An electron volt is the amount of kinetic energy needed to move an electron through one volt potential. Moving along the spectrum from long to short wavelengths, energy increases as the wavelength shortens.
Aug 10, 2016 · What is Electromagnetic energy? Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. The human eye can only detect only a small portion of this spectrum called visible light. A radio detects a different portion of the spectrum, and an x-ray machine uses yet another portion.
The Electromagnetic Spectrum. This unique NASA resource on the web, in print, and with companion videos introduces electromagnetic waves, their behaviors, and how scientists visualize these data. Each region of the electromagnetic spectrum (EMS) is described and illustrated with engaging examples of NASA science.
Oct 9, 2020 · This is because electromagnetic waves can transmit energy through a vacuum, or without a medium. Here are a few applications of electromagnetic waves in our lives. Radio waves: For communication uses, such as television communication and radio. Microwaves: Used in a microwave oven to heat meals, and for satellite television.

Dec 28, 2020 · Electromagnetic waves are produced across an enormous range of frequencies and wavelengths. Starting with low frequency (lower energy) and thus longer wavelength, the various types of EM radiation are: Advertisement. • Radio waves (about 1 m and longer): Radiofrequency EM radiation spans about 20,000 to 300 billion Hz.
